ABSTRACT
With growing economical activities and transportation needs in the city, Taipei, the capital of Taiwan, has been developing its metro system for the past 25 years. As tabulated in Table 1, the Stage I Taipei Rapid Transit System (TRTS), with about 93-km routes and 82 stations, was completed and set out for revenue services in July 2009 (while the first line started the operation in March 1996). For the Stage II, which is currently under construction and is scheduled to be completed by 2018, additional 87-km routes and 76 stations would be added to the system. By the completion of the TRTS network in the Stage III, a total of 7 major lines with over 270-km routes and 250 stations will spread over the Taipei Metropolis (Fig. 1).
